Single 5s exposure at ISO6400. Is it a satellite? Or did I actually capture incoming space dirt :)

If there are erratic changes in brightness then it's a meteor, but it seems (at first glance, anyway) to brighten (or fade, if it was going the other way) very steadily, which might suggest something artificial? Unless you're watching the sky at the time and notice the event, it can be hard to tell. Is there any way to figure out how fast it was moving? Can you trace the trail back to a known meteor shower radiant? You can sometimes positively identify a satellite using something like Starry Night.
Wow. Lovely! Well caught!!
